Treatment of Oral Premalignant Lesions With 5-ALA PDT
Completed · Phase 1/Phase 2
Conditions studied: Leukoplakia, Erythroplakia
In brief
Oral leukoplakia within the mouth is a visible white patch which can develop into cancer if not treated. There is no good treatment for these lesions, apart from surgery which is associated with significant side effects and physical deformation of the treated area. The investigators hypothesized that photodynamic therapy can be used safely and effectively to induce significant regression of oral leukoplakia.
